I had to Force the game to Stop via Task Manager.
So there was no Crash Report.

I cant find any Save/Load Options, without it to replicating it outside of Developer environment ... is to time intensive.

If the game creates Logs automatical, where can i find them?

I did not replicate the Error.
I dont have any Save. (Is there even a Save/Load Option?)

CoopMission (1/4) Black Day (First mission from the Main Game Expansion)
Played as Cybran.

I refit a SubCom seconds before and or while a cutscene started.
I was stuck in the "Do you want to remove the installed Modul - [Y/N]" Popup Window.

No Access to any UI Options.
No Shortcut functioning.
No Unit selectable.
Could move map via keyboard.
